1. Industry Overview

Laser interferometric 3D topography measurement systems use laser interference principles to measure optical path differences and determine physical quantities with high precision. The laser source is split into two beams by a beam splitter—one beam reflects off the measured microlens/wafer surface, the other off a reference mirror. When the two reflected beams converge, interference occurs. Any change in optical path difference between the two coherent beams sensitively causes interference fringe movement. By measuring fringe changes, the system precisely measures 3D topography, roughness, sagitta, and step height of the measured optical element.

Core System Components

• Laser source and Köhler illumination system

• High-definition imaging system

• High-speed image acquisition system

• High-precision vertical displacement system

• Multi-dimensional sample adjustment platform

• Interference-specific objectives

The system uses narrow-band high-stability laser as the core light source, with an integrated tube lens and interference optical path structure. Unlike traditional scanning equipment relying on piezoelectric ceramic Z-axis reciprocating scanning, the Mingcha Zhixin Qiuhou R series (MCZX) adopts a full-field single-exposure imaging architecture, paired with proprietary algorithm software for full-process control—efficiently completing non-destructive 3D topography inspection of silicon wafers and CPO optical communications microlens arrays.
